基于Tabu算法的双层圆柱面网壳结构的优化

Optimization of cylindrical latticed double-layer shell based on Tabu Search method

将Tabu搜索方法用于双层圆柱面网壳结构优化,以网壳造价最低为目标,对网格尺寸、网壳厚度、矢跨比等网壳结构参数进行了优化计算,算法采用二进制和十进制两种编码方案,并与经典的遗传算法网壳结构优化进行了比较,结果表明:Tabu搜索方法具有更强的全局寻优能力,是一种很有应用前景的网壳结构优化方法.

Tabu Search (TS) method is used for the optimization of cylindrical latticed doublelayer shell. Grid size, vault thickness and risetospan ratio of the shell are optimized under the condition of the minimized cost of the shell based on binary system or on decimal system. Simulation results show that the shell cost optimized with the TS method is cheaper than the one with the Genetic Algorithm (GA) method, and TS method will be a good candidate for the shell optimization in the future.
